Problem Description:

How to search for a file in a directory?

Solution:

Following example shows how to search for a particular file in a directory by making a Filefiter. Following example displays all the files having file names starting with 'b'.

import java.io.*;

class Main {
   public static void main(String[] args) {
      File dir = new File("C:");
      FilenameFilter filter = new FilenameFilter() {
         public boolean accept
         (File dir, String name) {
            return name.startsWith("b");
        }
      };
      String[] children = dir.list(filter);
      if (children == null) {
         System.out.println("Either dir does not 
         exist or is not a directory");
      } 
      else {
         for (int i=0; i7lt; children.length; i++) {
            String filename = children[i];
            System.out.println(filename);
         }
      } 
   }
}

Result:
